Shear span is defined as the zone where shear force is constant. The typical bending moment and shear force diagram of a uniformly loaded beam is given below. Since shear force is not constant between any span within the beam.
Hence the correct answer is option A.

Shear span is a term used in structural engineering to describe the region of a beam where the shear force is constant. The shear force is the force that acts perpendicular to the axis of the beam, causing it to bend or twist.
Explanation:
In a beam, the shear force is the result of the loads that act on the beam. It is maximum at the ends of the beam and decreases towards the center. The region of the beam where the shear force is constant is known as the shear span.
The shear span is important in the design of beams because it affects the shear capacity of the beam. If the shear span is too long, the beam may fail due to shear forces. On the other hand, if the shear span is too short, the bending moment may become too large, causing the beam to fail due to bending.
The shear span is also important in the calculation of the shear stress in the beam. The shear stress is the force per unit area that acts parallel to the axis of the beam. It is maximum at the ends of the beam and decreases towards the center.
Conclusion:
In summary, the shear span is the region of a beam where the shear force is constant. It is important in the design of beams because it affects the shear capacity of the beam and the calculation of the shear stress in the beam.
